TOOL-HANDLE.

To all whom, it may concern:

Be it known that I, I-IENRIGK SALZ, a subject of the Emperor of Germany,residing at Hoboken, county of Hudson, State of New Jersey, haveinvented a certain new and useful Improvement in Tool-H andles, of whichthe following is a specification.

My invention relates to an improved article of manufacture comprising atool-handle adapted to receive impact blows from a hammer or otherimplement while using the tool.

The object of my improved handle is to overcome the likelihood of thehandle splitting orbreaking during use of thetool. Further it isintended. thatthe head .or cap which is adapted to receive the blowsfrom a hammer may be renewable so that when the cap becomes mutilated orshattered so as to be less useful it may be unscrewed and a new capplaced on the end of the handle.

Inthe case of handles for tools provided with a tapered sliankm'yinvention comprises an internal plug provided with a ferrule within'thehandle so arranged that the shank is more firmly held in the handle andthe handle is not likely to split-in. use.

For tools in which the handle is inserted in a socket I have providedthe handle with an internal bore filled with a metal plug which isadapted to reinforce the handle, the plug being held in place by thescrew cap, which, in my device is adapted to be screwed into a ferruleon the upper end of the handle. In both cases the compression andfriction of the wood holds the handle to the tool.

In the accompanying drawings I have illustrated two forms of myinvention, Figure 1 representing the reinforced handle for socket toolsand Fig. 2 the reinforcedha'ndle for tapered shank tools.

Each of these forms,'it will be seen, is provided with a ferrule at theupper end into which is screwed the top cap.

Referring to the drawings, 1 represents the handle body which isprovidedwith an interior bore 2, through the axis of the handle, which iscounterbored at 3 as shown in Fig. 1, the bored out portion beingcompletely filled preferably with a steel pin 4c having a head 5 adaptedto fit the counterbore. The lower end of the handle in Fig. 1 is taperedat 6 to fit the taper of the tool 7 substantially as illustrated. Theupper end Specification of Letters Patent.

Application filed April 21, 1914. Serial No. 833,344. i

of the handle is turned down to a smaller diameter and is provided witha ferrule 8 which is secured to the handle by screw threads orotherisuitablemeans andiswide enough to permit a portion thereof toextend beyond the endjofthe handle. This internally threaded extendingportion of the fer- Iruleis adapted to receive the body portion of thetop-cap or head 9 which is threaded at 10 and preferably provided withan overhanging flange 11 substantially as illus trated. The outersurface and edges of the flange are preferably rounded and the materialof the cap or head may be of fiber or similar material adapted towithstand hammer blows. Preferably I insert, between the cap 9 and theupper end of the handle, a disk 12 of rubber or similar elastic packingwhich is adapted to cushion the blow and hold the reinforcing pin inplace.

Referring to Fig. 2 of the drawings, it will be seen that the handle 1is counterbored to a greater depth, or within perhaps an inch of thelower end of the handle, and this counterbore is adapted to receive aplug 13,

preferably of soft wood, which plug is, fitted at its lower end with aferrule 14 whose external diameter is substantially equiva? lent to theinternal diameter of the'counter bore 3. The plug is preferably made tofit tight in the counter bore and if desired may be held in p'lacebyglue or other suitable means. The lower ends of the handle and of theplug 13 are bored out in alinement with a small hole adapted to receivethe tapered shank 17 of the tool with which the handle is to be used.The lower end of the handle at 15 is provided =with an external ferrule16 which, as usual with this construction, is adapted to preventsplitting of thehandle. In securing the handle to the tool it will beunderstood that the handle is driven on to the shank which spreads andcompresses the handle proper at such a position as to receive and steadythe upper end of the shank 17 of the tool, so that it will practicallyprevent any possibility of the handle above the lower ferrule becomingsplit or shattered. In this form of device the upper end of the handleis provided with a ferrule 8 preferably screw threaded on to the upperend of the handle which may be of reduced diameter as illustrated. Thisferrule 8 as with the form 5, shown in Fig. 1, is adapted to receive ascrew threaded top-cap or head 9, which may be made of fiber or othersuitable material not likely to readily deteriorate or become fracturedwhen hammered upon during use of the tool. The cushion disk 12 betweenthe upper end of the handle and the cap 9 is also employed to assist incushioning the blow and holding the parts in close engagement.

From the description of my invention it will readily be understood thatthe tool handle may be manufacteured and sold in complete form and maybe attached by the user to the tool. It will further be apparent thattwo or more caps or heads may be supplied or bought separtely so thatwhen one head becomes battered up or broken it may be unscrewed and anew head substituted, this lengthening the life of the handle andextending its usefulness.

It will be understood that various forms of my improved handle may bemade to meet the demands, or to fit tools of various characters andvarious modifications in the structural detail may be made withoutdeparting from the spirit and scope of the claims.

1. As an article of manufacture, a tool handle provided with a centralcounterbore, a plug of penetrable material adapted to grip a forciblyinserted tool shank, said plug fitting said counterbore, a ferrule onthe lower end of and of the same outside diameter as said plug, saidplug being provided with a central hole while the lower end of saidhandle beyond the counterbore is provided with a hole of less diameterthan the counter-bore and coaxial with the hole in said plug, the shankof the tool being adapted to pass through the hole in the lower end ofthe handle and enter the hole in said plug.

2. As an article of manufacture, a tool handle provided with a centralcounterbore, a plug-of penetrable material adapted to grip a forciblyinserted tool shank, said plug fitting said counterbore, a ferrule onthe lower end of the plug, said plug being provided at its lower endwith a central hole, a ferrule on the lower end of the handle which isprovided with a hole of smaller diameter than the counterbore andcoaxial with the hole in said plug, a larger ferrule on the upper end ofthe handle, said last named ferrule being internally screwthreaded, anda cap externally screwthreaded and adapted to be secured to the handleby screwing it into said last named ferrule, the cap being adapted tohold said plug in place and to receive hammer blows, the shank of thetool being adapted to be inserted in the holes in said handle and plugsaid ferrules being adapted to prevent splitting of the handle at eitherend and at the middle.

3. As an article of manufacture, a tool handle provided with. a centralbore, a plug adapted to fit said bore, a ferrule of the same diameter asthe bore secured to the end of said plug, a ferrule secured to the upperend of said handle and internally screw-threaded, a flanged cap havingits body portion screw-threaded to fit the threaded ferrule, and anelastic disk within the ferrule between said cap and the end of thehandle and plug.

4. As an article of manufacture, a tool handle provided with an interiorbore extending axially into the handle, a plug member of soft woodfitting said bore and extending to within a short distance of the lowerend of said handle, a ferrule surrounding the lower end of said plug andfitting said bore, a ferrule on the upper end of the handle providedwith internal screwthreads, a top cap having a flange extending over thetop of said ferrule, the body portion being threaded and screwed intosaid ferrule and an elastic shock absorbing member between said cap andthe top end of said handle.

In testimony whereof, I have hereunto set my hand in the presence of twosubscribing witnesses. Y
